Direct the flow of water over the rocks in your stream or waterfall with Savio Black Foam. This convenient, black colored polymer expands to form a waterproof seal in cracks or voids between rocks and most construction materials. The foam's easy-to-use can makes it simple to point and fill, while the foam's black color discretely blends with liner and rocks. The foam is closed cell, and will not age, harden, or shrink. Additionally, it is safe for water gardens with fish and other aquatic life. It is perfect for filling and sealing holes in a variety of applications such as securing stone edging or containing gravel on bog shelves. This foam dries quickly. It is tack-free in 20 minutes and ready to trim in less than an hour. Each can delivers approximately 750 cubic inches of cured foam. Made in the USA.
